An SSL certificate is a digital certificate that verifies a website's integrity and enables an encrypted connection. SSL represents Secure Sockets Layer. It is a security protocol that makes an encrypted linked between a web server and a web browser.
Companies and organizations required to insert SSL certificates to their websites to secure online transactions and maintain user data private and secure. SSL keeps internet connections secure and avoids criminals from reading or changing data shared between two systems.
SSL operates by providing that any data shared between users and websites, or between two systems, remains impossible to read. It facilitates encryption algorithms to scramble data in transit, which avoids hackers from reading it as it is transmitted over the connection. This data contains potentially sensitive data including names, addresses, credit card numbers, or other financial details.
An SSL certificate serves as a credential in the online world. Each SSL certificate uniquely recognizes a particular domain (including thawte.com) and a web server. Trust of a credential is based on confidence in the organization that issued it. Certificate authorities have several techniques to verify data supported by individuals or organizations. Established certificate authorities, including Thawte, are familiar and trusted by browser vendors.
There are three types of SSL Certificates which are as follows −
Domain validated (DV)
DV certificates only test who own the site. It’s a simple process where the CA will send an email to the website’s registered email address to check its identity. There is no data about the organizations.
Domain Validation certificate is entirely provided and distributes a same browser perception with Organizational Validation certificates. It supports the advantage of being expressed directly and without any requirement for submitting enterprise paperwork. It creates Domain Validation certificates more goals for trades quickly requiring a lesser cost SSL and without any effort to submit enterprise records.
Organizationally validated (OV)
It can receive an OV certificate. A CA should validate specific data, including the organization, physical area, and its website’s domain name. This process generally takes several days. OV certificates have a limited level of trust and are the best choice for public-facing websites that manage with less sensitive transactions.
Extended Validation (EV)
This type of certificate is a must-have for websites that handle sensitive data. It has the largest level of security5 and is the simplest to recognize. It can issue an EV certificate, the CA implements an enhanced review of the applicant to improve the level of confidence in the business.
The review procedure contains the determination of corporate files, confirmation of applicant identity, and checking the data with a third-party database. Users can know if a website influences an EV certificate if the browser’s URL bar includes a padlock and the company name is recorded in green.
